This research study is a long-term follow-up to an earlier study of developmental care. For that study, high risk preterm newborns were randomly assigned to a standard care group, which received the standard care offered in the Newborn Intensive Care Unit (NICU) at the time, or to an experimental group, which received regular behavioral observations to determine if changes in their environment or care were needed. The purpose of the current study is to assess the functioning of these infants again, now that they are adolescents and to compare the groups to determine if the developmental care used in the original study is effective long-term.
